Product
Use + Advantages 

The FUX 3200 L1 UEWA spark
detector range is utilised to detect
sparks and flames in applications
where particularly difficult operating
conditions prevail. This has
been achieved by isolating the
detector housing with its complete
electronics from the optical window
using fiber optic cable.
This design ensures that the function
of the electronics, sensor, fiber
optic cable and lens, in cluding the
transmission is mon itored. Due to
this patented sol ution an absolutely
safe moni toring of sparks and flames
within machine components
and conveying systems is ensured.
The detector window consists of
special glass developed for both
ex treme conditions and the monitoring
of functions.

The short reaction time of <5 ms
is also impressiv.
The protective jacket of the fiber
optic cable is available in different
materials such as stainless steel,
plastic or a coated version.

The FUX 3200 L1 UEWA spark
de tector range is used mainly for
ma chine protection, particularly
within machine components.
Typical applications include:
– timber processing industry
– panel board presses
– electrostatic painting systems
– painting robots
– motor test benches
– machine tools
– pellet mills in
biomass power stations
– food industry
Aproximately 200 chipboard
presses world wide are effectively
protected by a combination of
FUX 3200 L1 UEWA and the
Minifog PressProtect fine spray
water system from Minimax.
These detectors have been used
with great success in gas turbines,
as even small oil leakage fires can
be safely detected, independently
of the ex tremely varying tempera -
tures in the exhaust bearing tunnel. 

+ The unique isolation of the electronics
from the optical window by a fiber
op tic cable ensures an operating
temperature range from –20 °C up
to +200 °C and supersedes a costintensive
detector cooling system
+ Patented optics visibility monitoring
against dirt
+ Patented function monitoring for all
sensors and evaluation electronics
+ Highest functional safety ensured by this
monitoring system. High reliability whilst
simultaneously reducing ope rating costs
+ For object monitoring, reaction times
in the ms range can be achieved
+ Ex-classification in accordance with
ATEX 94/9/EG Category 1 D and 3D
for the zones 20 and 22
+ Special installation device for rapid
cleaning of window, even during
operation
+ Practically flush installed optics
+ HV-proof up to 110 kV for electro -
static painting systems
+ Applications with high continuous
operating temperatures up to 200 ºC
and strong environmental conditions
